1 Claim. (Cl. 11o-18).

Thls invention relates to improvements in incinerators of the type installed in apartments, public buildings, etc., for the disposal of waste material such as garbage and other refuse. Banks and similar institutions use incxnerators to burn up documents and papers. Such material, instead of being completely destroyed, sometimes passes up the chimney llue and is discharged intact therefrom. Such occurrences give rise to complications and rellect on the institutions which had custody of -the papers.

The object of the present invention is to provide an incinerator of simple construction which can be economically made in which the material burned in it will be completely consumed so that no odors from burning garbage and the like and no unburned matter can escape from the ue. Another object is to provide a simple means for sterilizing the ue. A still further object is to provide an incinerator the uses of which will meet the requirements of municipal ordinances.

These and other objects of the invention will appear in the following specification in which I will describe an embodiment of the invention and its operation.

Referring to the drawings,

Fig. 1 is an elevation partly in section of an incinerator which is made according to and embodies my invention.

Fig.2 is a sectional plan view taken on the line 2-2 of Fig. l.

Fig. 3 is a sectional view on an enlarged scale of the structure shown in Fig. 1.

Fig. 4 is a similar enlarged scale sectional view of an upper portion of the same structure.

designates a vertical rectangular structure in which is -a dividing Wall 11 which separates the interior into a chute 12 and a flue 13.

Refuse openings 14 into the chute, each of which has a removable cover, are provided at each floor of the building in which the incinerator is installed. Vertically spaced orifices 15 are formed in the dividing wall 11 for a purpose which will be described hereinafter.

The dividing wall terminates at 11A and spaced below it is a dellecting baille plate 16 which projects at an inclined angle from one of the walls of the chute 12.

20 designates a base upon which the structure 10 is erected. An ignition chamber A is formed between the wall of the chute from which the baille plate projects, a vertical wall 21 and side walls not shown. The wall 21 terminates at 21A at substantially the same level as that of the lower end 11A of the dividing Wall. Spaced above it a horizontal ceiling 22 projects from the dividing wall.

A lire grate 23 forms the base of the ignition chamber. 24 is a clean-out door below the grate and a re door (not shown) may be provided above the grate. A re I1l 6 zz1e 25 is positioned immediately below the baille plate 21,937,603 Patented May 24, 1960 An intermediate vertical wall 30 extends downwardly from the end of the ceiling 22 toward the base 20, spaced laterally from the wall 2-1. The lower end of this intermediate Wall is spaced vertically from the base 20. 31 is a vertical end wall laterally spaced from intermediate wall 30 which rises from the base 20 to a point above the ceiling 22. From its upper edge a second ceiling 32 extends to a wall of the flue 13 which terminates at 13A. B and C are two parts of a double combustion chamber. 33 is a clean-out door at the base of this double chamber.

The upper ends of the chute and the liue terminate at the same level, Figs. 1 and 4. 40 is a damper, pivoted at 41. In the' position shown in Fig. 1 and in full lines in Fig. 4, this closes the upper end of the chute 12 and opens the upper end of the ue. In the position shown in dotted lines in Fig. 4, it closes the upper end of the flue 13 and opens the upper end of the chute.

D is a chamber above the chute and the llue, the upper end of which opens into a screened cage 42.

Garbage and other waste matter put -into the chute through the openings 14 fall through the chute and are deected by the baffle plate 16 into the ignition chamber A. There it is ignited by the ame from the nozzle 25. There it burns on the grate. Combustion continues in `the chamber B land is thoroughly completed in the chamber C.

During this operation, the top of the ue is open and the hot gases pass through the chamber D and the screened cage 42 into the free atmosphere.

Should any of the material lodge in the chute and become ignited during this operation, the smoke produced thereby will be drawn trhough the oriiices 15 into the flue.

In order to occasionally sterilize the chute, the damper 40 is moved to close the upper end of the flue land open the upper end of the chute. Then the heat from the tire nozzle passes up the chute and burns ot foreign matter from its walls.

Various modifications in construction, mode of operation, method and use of an invention may and do occur to others, especially after benetting from knowledge of such a disclosure as that herein presented of the principles involved, but the invention itself is not conlined to the present showing.

What I claim is:

An incinerator comprising a substantially verticalstructure having a chute and an independent flue, a defleeting bathe plate at the lower end of the chute, a furnace at the base of said structure, said furnace having an ignition chamber with which the chute communicates permanently, a re nozzle under the baille plate and a combustion chamber permanently communicating with the flue and a single damper for closing the upper end of either the chute or the flue.
